Wide Review of substantive changes

None of the substantive changes since CR1 are related to Accessibility, Internationalization, Architecture, or Privacy. Some Security-related changes have been made, but the Security review is pending the creation of Security Interest Group. We have written to each group above to get confirmation on if they concur with our analysis.

With respect to wide review, changes to each specification has been circulated on a weekly basis to the W3C Credentials Community Group, which contains over 560+ individuals, with a number of them providing continued feedback since CR1. For example:

https://lists.w3.org/Archives/Public/public-credentials/2024Oct/0031.html

The test suites run on a weekly basis and implementers actively track how their implementations are performing. Ecosystem reports are also available and are tracked and commented on by organizations adopting vendor solutions:

Multiple implementers have also reviewed changes and have confirmed that they will implement or plan to implement all substantive changes since CR1.

I don't see any wide review requests for those changes, including horizontal reviews. Some changes impact security/privacy and would be good to get a review of those.
